DLR allows: To uncover the fullavailable line capacity (aka ampacity ) To get closer to the limit, with the same level of security
From darkness to light.

Sag (Clearance) is the most critical limit to the operation of anoverhead-line
Typically maximum sag will be reached at temperatures belowmaximum conductor temperature Direct sag measurement is the safest monitoring method REAL-TIME measurement of Sag: the only DLR system closing the
loop with a direct measurement of Sag

DLR Applications
19
REN integration
Accelerates wind farms integration (no need for new lines)Less curtailment => higher revenue for wind farms
Infrastructure deployment and optimizationQuick, significant, easy to deploy extra capacity until newinfrastructure is in place or while maintenance is performed
Market liquidity and security of supply
Increases X-border capacityGives visibility and transparency on available capacity oncritical linesIncreases security of supplyIncreases markets liquidity and price convergence
8/10/2019 Ampacimon Presentation Sth Am
20/34
Maximize usage of existing OVH lines Particularly interesting for wind farms Example:
A TSO needs to connect 9MW extra wind farm capacity ona 63kV line (static rating 430Amp)New OHL would require new 24m investment, 5 yearsplan and deploymentdone in 3 months, costing 400k
Gains up to 50% in RT sufficient to debottleneck the line
REN integration
8/10/2019 Ampacimon Presentation Sth Am
21/34
Increase security of supply with existing assets
Improve interconnections Example:
Belgium, faced with potential generation shortage needsto maximize interconnections with F and NL
Equip all 8 interconnections with and
D-2 forecast allows to increase total (3000MW) importcapacity by 10-15%
Up to 30% in Real TimeDeployed in 2 months, increase security of supply by300MW !
Infrastructure optimization
8/10/2019 Ampacimon Presentation Sth Am
22/34
Monitors true available capacity, data can be shared withoperators/market participants Reliably forecast bottleneck interconnectors Increases price convergence at a fraction of the cost and time
of new OHL projects Can be combined with other flexibility devices
